I would like to show you how to make a poster to promote your band or upcoming gig by using free software available on the internet. Using these techniques you will be able to obtain professional graphic results. First of all, you will need to acquire and organize your information that you will be placing on your band poster. Obtain the name of the gig, the names of the bands that will be playing, the location, time, and admission fees and any kind of age restrictions.
For the design of the poster, start with getting a feel for the design of band posters by Googling "band posters". See what you like, but try to focus on a simple and bold design. Try to incorporate colours, simple images, and emulate the theme of the gig. For example, if it's a hard rock gig, consider a deserted factory theme, or a vintage car look, or a rebellious pose of the band. Remember to use simplicity in your poster design as this will be more of an eye catcher than a complicated layout or theme.
